Hello Daniel!
If you use our Dorico playback templates for the SYNCHRON-ized Special Editions, VelXF is turned on by default.
The additional sound at the end of your example is a release sample. If your note would be one (or more) second shorter, it would probably fit. If it would be one second longer, it wouldn't be triggered anymore. So I would change the playback note length on the Dorico Play page. Such occurances shouldn't happen too often, unless you try to trigger them on purpose.
Best regards,
Andi
